Hi,
I like the background image that you have used for the menu scene. It really gives the feeling of war. You have used a font style for the title of the menu scene which is highlighted on the screen. That's a good technique. Also, you have used hovering effects on buttons, so that users can identify the system changes. However, I think you could have increased the font sizes because it's so hard to see the texts on the buttons.
When it comes to your object scene, you have done a great job of creating the object. But, here also button texts are too small and it's so hard to identify the texts. That's the only issue I see in your scenes.
Thanks !!
